SPECIFICATION forming part of Letters Patent No. 758,432, dated April 26, 1904.

Application iiled January 9, 1903. Serial No. 138,429. (No model.)

T0 all whom. t 71u07/ concern.: l

Be it known that I, THOMAS A. EDIs'oN, a citizen of the United States, residing at Llewellyn Park, Orange, in the county of Essex and State of lNew Jersey, have invented a certain Oonveyers, of which the followingv isa description.

My invention relates to an improved appa-v ratus by means of which material in bulk, like cement or cement mixtures, Acan be effectively removed vfrom stock-houses having substantially level floors, thereby overcoming the expense of building stock-houses with hopperlike bottoms and with tunnels beneath the same for Vcon-taining the conveying devices.

. By the use of the present invention I am enabled to build stock-houses with solid fiat floors composed, preferably, ofconcrete, requiring onlya light and relatively inexpensive protecting-shed for covering the material, thus reducing the expense to a minimum, while at the same time the material can be removed from the stock-house practically with the same facility as when the stock -house is formed of a series of hoppers with a tunnel beneath them containing the conveying devices, as at present. c

, My object, therefore, is vto provide a simple and effective conveyer by means of which material can be removed in bulkv from any part of a stock-house having a substantially fiat bottom, all as I will more fullyhereinafter describe and claim.

Broadly speaking, the invention consists of one or more conveyers' arranged' to work as close as practicable to the bottom of the stockhouse, so as to remove material to one orbothv of the sides thereof, combined with one or more auxlhary conveyers receiving the material so removed and conveying it tothe de-v .conveyers 5 5, two being shown.

In carrying the invention into effec-t I employ details of construction, some of which understood,attention is directed'to the accompanying drawings, forming part of this speciflcation, and in which- Figure lis a diagrammatic side view, partly in section,showing the invention in its preferred form, with a single auxiliary conveyerv arranged in a pit near one side of the stockhouse; Fig. 2, a corresponding plan view;

Fig.A 3, an enlarged plan view of the main conveyers and bridge-for carrylng the same, showing the motors for operating the conveyers and bridge, respectively; Fig. t, an velevation of the same parts; Fig. 5, an end view of the bridge and conveyers, viewing the same from the drive end; and Fig. 6, a corresponding view of the delivery end.

In all of the above views corresponding parts are represented by the same numerals of reference.

, Referring first to Figs. 1 and 2, the stockhouse is provided with a bottom 1, made, prefl at the bottom at `one or both of the sides.:

Movable longitudinally of the stock-house is a bridge 4, the preferred details of which Vwill be presently described, carrying one or more Ordinary screw conveyers are illustrated. These conveyers work as close as practicable to the bottom 1 and deliver material deposited on the ioor l to the pit 3. Mounted in this pit is aconveyer 6, illustrated as anordinary worm or screw and delivering material to a conveyer 7, shown as a conveying-belt.

From the two views to which attention has been particularly directed the general scheme will be understood, material being deposited on the Hoor l in any suitable way'to accumulate in a series of large conical piles or a single mass, and being transported laterally so as to be deposited in the pit 3, from which it is re' moved by the conveyer 6 to the conveyer 7 IOO The preferred details of construction are illustrated in the remaining views, to which attention is now directed.

The bridge 4 comprises two lower chords 8 8, connected together by cross-beams 9 and diagonal braces 10, and two upper chords 11 11, connected together by cross-beams 12 and diagonal braces 13. The upper and lower chords at each side are connected together by vertical beams 14 and diagonal braces 15, so that the whole bridge constitutesa very light but rigid structure. The bridge as a whole is mounted on wheels 16, carried on tracks 17, so as to be movable longitudinally of the stockhouse. The tracks 17 are mounted on beams 18, arranged at the side of the stock-house, as shown. Extending entirely across the bridge is a drive-shaft 19, carrying a pinion 2O at each end, said pinions engaging racks 21., secured to the track-supporting beams 18. The shaft 19 is driven by a motor 22, preferably an electric motor, through suitable gearing 23. By operating the motor 22 in either direction it will be obvious that the bridge as a whole may be caused to travel in either direction longitudinally of the stock-house at a slow speed. The conveyers 5 are mounted in bearings 24, carried by the,lower cross-beams 9, and each is provided at one end with a sprocket-wheel 25, driven by a sprocket-chain Q6 from an operating-shaft 27, located vertically above the drive-shaft 19. This operating-shaft 27 is driven by a motor Q8, preferably an electric motor, through gearing Q9. By operating the motor 28 it will be obvious that the two conveyers 5 will be simultaneously rotated to direct material toward the pit 8. It will be of course understood that where a pit is used at each side of the stockhouse the main conveyer or conveyers will be oppositely pitched from the center to either side, so that material will be conducted equally to both of the pits.

In operation the material is accumulated in the stock-house in a single large conical pile or in a series of piles, andi the motor 28 is operated to drive the main conveyer or conveyers. These conveyers engage the material and transport it toward the pit 3, from which it is removed by the conveyer 6. When necessary, the motor 22 is operated to shift the bridge slightly sidewise, so that the conveyers 5 will be always kept supplied with material.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows:

1. Apparatus for removing material in bulk from stock-houses, having substantially fiat bottoms, comprising in combination a pair of bodily-movable main conveyers feeding in the same direction and extending parallel with and closely adjacent to the bottom, so as to directly move the material thereon, and an auxiliary conveyer for receiving material from the main conveyers, substantially as and for the purposes set forth.

2. Apparatus for removing material in bulk from stock-houses having substantially flat bottoms, comprising in combination a pair of main conveyers feeding in the same direction and extending parallel with and closely adjacent to the bottom, so as to directly move the material thereon, means for moving the main conveyer longitudinally of the stock-house, and an auxiliary conveyer extending longitudinally of the stock-house for receiving material from the main conveyers, substantially as and for the purposes set forth.

3. Apparatus for removing material in bulk from stock-houses having substantially flat bottoms, comprising in combination a bodilymovable bridge braced against vertical strains, a main conveyer carried by the bridge and engaging material on said bottoms, and an auxiliary conveyer receiving material removed by the main conveyer, substantially as and for the purposes set forth.

4. Apparatus for removingl material in bulk Vfrom stock-houses having substantially Hat bottoms, comprising in combination a bridge, braced against vertical strains, means for moving the bridge longitudinally of the stockhouse, a main conveyer carried by the bridge and engaging material on said bottoms, and an auxiliary conveyer extending longitudinally of the stock-house for receiving material removed by the main conveyer, substantially as and for the purposes set forth.

5. Apparatus for removing material in bulk from stock-houses having substantially flat bottoms, comprising in combination a bridge, means for moving the bridge longitudinally of the stock-house, a pair of main conveyers carried by the bridge, feeding in the same direction and extending parallel with and closely adjacent to the bottom to directly move the material thereon, and an auxiliary conveyer extending longitudinally of the stock-house, forreceiving material removed by the main conveyers, substantially as and for the purposes set forth.

6. Apparatus for removing material in bulk from stock-houses having substantially fiat bottoms, comprising in combination a bridge braced against vertical strains, a motor for bodily adjusting the same, a main conveyer carried by the bridge and engaging material on said bottoms, a separate motor carried by the bridge for operating the main conveyer,
